Portable USB low frequency massager

The present invention relates to an electronic massage device, and more particularly to a portable USB low frequency massager.

Many portable electronic massage devices have appeared on the market, such as many products named "low-circulation therapeutic devices", which are conceptually an electric therapy device that is generally used for physical rehabilitation or for relieving pain. "When low-frequency is used for treatment, the weak current is applied to the human body in a low-frequency manner. The electrode piece directly stimulates the muscle and muscle nerve endings to feel the receptor, and the muscles will unconsciously contract, causing fatigue or injury. Sore muscles, nerves relax, promote local blood circulation, reduce or soothe pain. (Wiki)

The utility model utilizes a widely-used power supply device with a USB TYPE-A female seat to solve the problem that the conventional technology is not easy to carry, thereby achieving a low-cost, small-sized, easy-to-carry, and more convenient portable USB low frequency. massager.

First, please refer to FIG. 1 , a schematic diagram of the structure of the portable USB low frequency massager and the system thereof, comprising: a power supply device 10 , a portable USB low frequency massage device 20 , a connecting line 30 and an electronic massage patch 41 , 42 . . In Fig. 1, the portable USB low frequency massager 20 is inserted into the USB TYPE-A socket 12 of the power supply unit 10 via the USB TYPE-A male 21. The microcontroller in the portable USB low frequency massager 20 records a plurality of waveform generation modes, and the first control button 24, the power button 25, and the second control button 26 control the starting and output voltage magnitude (intensity) of the power source. And by the indicator group 28 to indicate the current voltage magnitude (intensity).

In an embodiment, since the waveform generation mode in the portable USB low frequency massager 20 is preset, the user does not need to control the waveform generation mode, and the microcontroller automatically switches according to the preset mode switching. Users can feel the different electronic massage effects brought by different frequency switching (waveform mode).

In another embodiment, since the waveform generation mode in the portable USB low frequency massager 20 is preset, the user can select the waveform generation mode by operating the first control button 24 and the second control button 26, and The waveform generation mode is sequentially output by the microcontroller according to the result selected by the user. When the user confirms the current waveform generation mode, the cut can be stopped. Change to achieve the effect of your favorite electronic massage mode.

Next, please refer to Figure 2, the functional block diagram of each device of the portable USB low frequency massager and its system. Among the power supply devices 10, there are a power supply unit 11, a USB TYPE-A female 12, and a USB control chip 13 which are common to all power supply devices. The power supply unit 10 can be a mobile power source, a computer, a notebook computer, a power outlet, and the like.

In the portable USB low frequency massager 20, it comprises: a USB TYPE-A male 21, a microcontroller 22, a boosting circuit 23, a first control button 24, a power button 25, a second control button 26, a switch 27 with indicator group 28, etc. The USB Type-A male 21 is connected to a power supply unit 10 having a USB Type-A female seat for taking power. The booster circuit 23 is for boosting the power taken by the USB Type-A male 21. The changeover switch 27 is connected to the booster circuit 23 and the electronic massage patches 41 and 42. The power button 25 is used to switch the activation and deactivation of the portable USB low frequency massager 20. The microcontroller 22 is connected to the USB Type-A male 21, the booster circuit 23, the changeover switch 27, the power button 25 and the first control button 24, the second control button 26, and the indicator group 28. The microcontroller 22 stores a plurality of sets of waveform generation modes. When the power button 25 is turned on, one of the group waveform generation modes is selected to control an output voltage of the booster circuit 23 and an output frequency, and the switch 27 is controlled. The discharge mode of the electronic massage patches 41 and 42 is used to perform an electronic massage operation. When the first control button 24 and the second control button 26 are operated, the microcontroller 22 adjusts the magnitude of the output voltage.

The indicator group 28 is connected to the microcontroller 22 for indicating the state of the output voltage, that is, the intensity state. For example, the output voltage has a fourth-order voltage output, and four LED indicators can be configured. That is, the indicator group 28 is composed of four LEDs. When the user controls the first control button 24 and the second control button 26 to adjust the magnitude of the output voltage, the four LED indicators indicate the magnitude of the output voltage adjusted by the current user.

Seconds/times..., and so on. The second mode uses the first interval of 1 second, followed by an interval of 0.5 seconds between the five pulse waves, and then, after another 2 seconds, repeats the aforementioned mode. The second mode is a waveform generation mode in which a long period is mixed.

In Fig. 3B, the third mode is a waveform generation mode of continuous pulses, that is, a pulse wave is generated every 20 milliseconds (ms) for a total of 2 seconds. Then, after an interval of 1 second, repeat again and continue to cycle this mode. The continuous pulse waveform generation mode adjusts the interval time (20 milliseconds) and the interval between each successive pulse (1 second).

The fourth mode is a waveform generation mode of a mixed continuous pulse, that is, a waveform generation pattern of a plurality of consecutive pulses of different intervals is mixed. In the embodiment of the fourth mode, the waveform generation mode of four consecutive pulses of 40 msec interval, 30 msec interval, 20 msec interval, and 15 msec interval is mixed, and the waveform generation modes of the four consecutive pulses are each generated 4 After the second, the waveform of the next continuous pulse is generated, and the loop continues. Again, this The pattern can also be repeated once after each complete cycle, after a large interval (such as a 1 second interval in the third mode). The waveform generation mode of the continuous pulse of the mixed interval time can arbitrarily select different interval times, thereby generating a plurality of different combinations.

The 3A and 3B drawings only show four waveform generation modes. For other embodiments, any mode combination is possible, and the present invention is not limited to the waveform generation modes listed in FIGS. 3A and 3B.

At rated time, one of the other waveform generation modes is adjusted to control the output of the booster circuit 23.

In still another embodiment of the present invention, the microcontroller 22 selects the waveform generation modes by the first control button 24 or the second control button 26, when the first control button 24 or the second control button 26 is continuously pressed. At two times, one of the other waveform generation modes is adjusted to control the output of the booster circuit 23.

In still another embodiment of the present invention, the microcontroller 22 selects the waveform generation modes by the first control button 24 and the second control button 26, and the first control button 24 and the second control button 26 are simultaneously pressed. At the next nominal time (e.g., 1 second, 2 seconds, or 3 seconds), one of the other waveform generation modes is adjusted to control the output of the booster circuit 23.

In still another embodiment of the present invention, the microcontroller 22 selects the waveform generation modes by the first control button 24 and the second control button 26, and the first control button 24 and the second control button 26 are simultaneously continuous.
